Product Positioning

The 3RT2024-1AG24 is an enhanced auxiliary contact version of the Siemens SIRIUS 3RT2 series. The coil voltage is 110V AC (50/60Hz), and the main circuit maintains the same specifications as the S0 frame and AC-3 rated 12A/5.5kW (400V). The biggest difference from the basic model in the same series is that it has 2 sets of NO + 2 sets of NC, totaling 4 instantaneous auxiliary contacts built into the contactor body. When the control panel needs to simultaneously obtain multiple outputs such as operating status indications, upper-level monitoring signals, and interlocking circuits, the space and wiring for external auxiliary contact sockets can be eliminated, as these are directly provided by the contactor body.

Core Product Advantages and Features
Four sets of auxiliary contacts are in place at once.
It has four built-in instantaneous auxiliary contacts (2NO+2NC) to simultaneously meet the multiple output requirements of indicator lights, monitoring signals, and interlocking circuits.
110V Dual-Frequency Coil
The coil supports dual-frequency power supplies of 50Hz and 60Hz, adapting to the control voltage requirements of equipment from different sources and production lines across regions.
No auxiliary module required
Compared to the standard 1NO+1NC version, it eliminates the need for purchasing and installing external auxiliary contact sockets, thus shortening wiring time.
Main circuit specifications remain unchanged
The AC-3 rated 12A/5.5kW maintains the same frame size as the S0, and existing installation and power distribution designs can be directly used.
